Selective Laser Melting Machine SLM 125

Accurate, compact and highly performant options for fast results. For production of highly complex components in research and development.

  • SLM 125

The Selective Laser Melting Machine SLM 125 offers a build envelope of 125 x 125 x 125 mm³. The flexibly applicable machine with high productivity has been designed for quick results in the research and development sector, as well as for the production of smaller build parts. In addition, the SLM 125 provides a build volume reduction of 50 x 50 x 50 mm³ thus decreasing the amount of powder by 80%.

The Selective Laser Melting Machine SLM 125 produces high-quality metal build parts using 3D-CAD data. The precise and economical machine is a winning solution, suitable for small lot, as well as in the field of research and development.The highest build rates in this class are achieved thanks to the patented bidirectional coating. The machine concept is impressive thanks to its patented process gas filtration and its safety. The adjustable gas flow allows optimal process properties with low gas consumption.

The SLM 125 is available with an optional software for reading CAD/STL data or slice data for configuring the process-specific and build part specific parameters. The open operation concept enables the construction processes to be carried out individually and customized manually. Stainless steel, tool steel, cobalt-chrome, nickel alloy, aluminium or titan can be processed.

Thanks to the machine’s compact design, with few powder-transporting components, materials can be changed quickly and easily. With a variety of options and expansion possibilities, the system can be adapted to individual customer requirements.

The Powder Sieving Machine PSM is a perfect complement to the SLM 125 machine. During the sieving process the rough particles are sieved out and are seperated in an overflow bottle. The reusable metal powder, which has the defined grain size, is transported to the storage container and can be directly used again.
